Anakata has formed a technology partnership with the Dutch wind turbine manufacturer EWT – the world’s leading turbine supplier for localised energy generation and repowering - to collaborate on the development of next-generation blade technology.
Anakata has been selected as a finalist of the 2018 Shell Springboard low-carbon innovation awards. In March Anakata will compete alongside 15 other finalists and present our advanced aerodynamic upgrade technology for wind turbines.
Are you unlocking the potential of every installation?
Every rotor can be improved and very rarely is a turbine operating at its design limit. Anakata’s range of retrofit aerodynamic add-ons will be tailored to your turbine model to maximise energy capture and reduce noise. Our wide selection of devices means that you can customise site installation on a turbine-by-turbine basis.
Our next-generation of add-on devices are inspired by cutting-edge Formula One technology and include winglets, tip extensions, vortex generators, serrations, gurney flaps, and other airflow controls.
Anakata uses the latest design and manufacturing techniques and has field tested several styles of add-on technology with MW-class OEMs.
AEP gains of up to 5% can be achieved with a short payback period of typically less than 2 years.
Anakata will undertake a comprehensive evaluation of your wind turbine to determine its potential for aerodynamic upgrade.
Typically this will involve the laser-scanning of the blade surface followed by construction of a detailed Blade Element Momentum model (BEM) of the turbine and full 3D CFD analysis of the entire rotor.
This allows us to understand the performance of the blade from root to tip and select from our comprehensive range of add-on devices, which will then be tailored to the specific blade.
Power performance analysis of the upgraded turbine is carried out using the industry-standard methods of comparing 3-6 months of SCADA data of the baseline turbine
Is your rotor working hard enough for you?
The rotor is the first phase of the energy transformation process from kinetic wind energy into mechanical torque, and as such is where investment in technology should be maximised. Aerodynamics is overlooked by many wind turbine designers because they do not understand what is possible; as such they continue to use out-dated technology and design methods.
Compared to blades using standard aerofoils (e.g. NACA/FFA/DU), Anakata blades produce up to 3% more AEP and are up to 3dB quieter, or 25% lighter.
Anakata designs holistically using a combination of industry-standard BEM modelling, advanced full-rotor 3D CFD methods, and wind tunnel testing. We have experience of testing in a number of state-of-the-art wind tunnels including Deutsche WindGuard, Cologne KKK, Stuttgart LWK, Virginia Tech., Mercedes F1, and Williams F1. We use a variety of testing techniques including full 3D model motion systems and infrared boundary layer visualisations.
Our wealth of design experience allows us to optimise blades to your requirements to achieve the best compromise of AEP, loads, and cost.
Trying to break the technology curve with your next rotor?
Anakata is your partner of choice for advanced blade technology development. Whether it is evaluating and progressing your own designs or licensing our unique Formula One-inspired technology, we can help you stay ahead of the competition.
We are specialists in novel aero-structural concepts, aero-elasticity for load control, fluidic logic, and cutting-edge composite design.
There is more money spent globally on aerodynamics R&D in Formula One than in the aerospace and wind turbine industries combined, yet technology transfer is scarce between these industries. Anakata UK is creating a fusion between these fields.
After technical inspection by the UK Government as well as industrial and academic experts, Anakata has been awarded a grant by the UK Department for Energy and Climate Change to develop a 15m-diameter advanced technology demonstrator wind turbine rotor. The blades for this prototype will be installed in the UK to showcase some of our design philosophies and blue-sky development.
Developed by Formula One aerodynamics and materials engineers, Anakata’s patented ‘Accelerator Technology’ and ‘microdownstream’ uses leading-edge technology to create a turbine that is more efficient than any other of its size.
The patented shroud designs of Anakata’s wind turbines not only maximise efficiency but also offer near-silent operation. This unique system significantly reduces operational noise as well as provides more visibility to wildlife, enabling wind power to be generated in areas where it was once considered unsuitable. This unrivalled innovative technology in the wind turbine market enables small-scale wind generation to become economically and environmentally viable.
Anakata has designed several high performance blades of varying lengths for microturbine use. Combining class-leading aerodynamics with state-of-the-art composites, Anakata produces the most efficient blades in the world.
